Abstract: Os oleos essenciais sao principios odoriferos armazenados em celulas especiais da planta. O oleo essencial no genero Hyptis e usado como anestesico, antiespasmodico, antiinflamatorio e pode induzir aborto em doses elevadas. O objetivo deste trabalho foi avaliar a influencia da sazonalidade no teor e composicao do oleo essencial de Hyptis marrubioides. O delineamento experimental foi inteiramente casualizado, com quatro tratamentos (inverno, primavera, verao e outono) e seis repeticoes, totalizando 60 plantas. O oleo essencial foi extraido por hidrodestilacao, em aparelho de Clevenger. A analise qualitativa do oleo essencial foi por cromatografia em fase gasosa (CG/EM). Na estacao do verao, as folhas das plantas de H. marrubiodes apresentaram os maiores teores de oleo essencial. Nas demais estacoes, os teores de oleo essencial obtidos foram semelhantes entre si. Os componentes majoritarios no oleo essencial foram os monoterpenoides α-tujona e β-tujona. As concentracoes relativas dos picos correspondentes a β-tujona nao apresentaram diferencas consideraveis nas quatro estacoes. Os sesquiterpenoides oxigenados (cedrol e cariofilenol) e nao-oxigenados (α-copaeno, β-cariofileno, germacreno D e cadaleno) foram encontrados em menores quantidades no oleo essencial, entretanto observam-se diferencas quantitativas ao longo das estacoes. Essential oils are odorous principles stored in special plant cells. The essential oil in the Hyptis genus is traditionally used as an anesthetic, antispasmodic, antiinflammatory, and can induce abortion in high doses. The purpose of this work was to evaluate the influence of seasons in essential oil content and chemical composition of species H. marrubioides. A completely randomized complete design was used with four treatments (winter, spring, summer and autumn) and six replications, totaling 60 plants. The essential oil was obtained by hydrodistillation with a Clevenger apparatus. The qualitative analysis of the essential oil was performed by gas chromatography (GC/MS). In summer, plant leaves showed higher essential oil content. In the other seasons, essential oil content was similar. The majorcompounds in the essential oil were monoterpene α-thujone and β-thujone. The peak relative concentrations of β-thujone did not show considerable difference among the seasons. The oxygenate sesquiterpenoids (cedrol and caryophyllenol) and not oxygenate (α-copaene, α-caryophyllene, germacrene D and cadalene), were found in lower quantity in the essential oil; however, quantitative differences were observed over the seasons.

Abstract: this study evaluated the effect of light, temperature, physiologic stage at harvest and length of time on the germination of hyptis marrubioides seeds. two trials were conducted. the first experiment was performed immediately after the seed harvest and consisted of a 2 x 3 x 3 factorial design with 2 environmental conditions (light and dark), 3 temperatures (20, 30 and 20/30oc) and 3 seed harvest times (green colored seeds, light brown seeds and dark brown seeds). the second experiment was conducted in the presence of light at a temperature of 30oc and consisted of a 4 x 3 factorial design, with 4 storage times (0, 6, 12 and 18 months) and the 3 three harvest physiologic stages used in the previous experiment. both of the experiments were conducted in randomized blocks, with 4 replications of 100 seeds. light did not affect germination. by contrast, a temperature of 20oc retarded the germination process, although the percentage of germinating seeds was not affected. seed storage and the different harvest physiologic stages affected the germination velocity index (ivg) and the germination percentage. seeds that were harvested at the more mature stage (dark brown color) could be stored for up to 18 months.

Abstract: ocimum basilicum l. cv. maria bonita is a medicinal aromatic plant of the lamiaceae family, it is rich in essential oils with high industrial interest. the present work aimed to study the influence of leaf processing (whole and ground leaf) in two drying types (oven-drying at 38o c and room temperature using moisture dryer) on the content and chemical composition of the essential oil. a completely randomized design was used with 4 treatments and 6 replicates. the essential oil obtained by hydrodestillation of the leaves was analyzed by gc and gc/ms. the results show that the drying type and the processing of the leaf influence the content and chemical composition of the essential oil. high amounts of linalol were obtained when the leaves underwent dry processing. the oven-dried conserved the aroma and the green color of the leaves, preserving the original characteristics of the cultivar.

Abstract: context and objective: the use of pedicled myocutaneous flaps in head and neck reconstruction is widely accepted. here we describe our experience with infrahyoid flaps (ihfs) employed to cover surgical defects in the oral cavity and oropharynx in patients with benign and malignant tumors. the aim was to evaluate the success rate for infrahyoid myocutaneous flap procedures performed at a single institution. design and setting: retrospective study, at the head and neck surgery service, unicamp. methods: fourteen ihfs were used to reconstruct surgical defects in eleven men (78.5%) and three women (21.5%) with a mean age of 66.4 years. the anterior floor of the mouth was reconstructed in nine patients (64.2%), the base of tongue in three (21.4%), the lateral floor in one (7.1%), and the retromolar area (7.1%) in one. thirteen patients (92.8%) had squamous cell carcinoma (scc) and one (7.2%) ameloblastoma. the disease stage was t3 in eight (61.5%) of the scc cases and t4 in five (38.5%). results: no patient presented total flap loss or fistula. the most common complication was epidermolysis, which delayed the beginning of oral ingestion. the patients with scc received postoperative radiotherapy without major consequences to the flap. conclusion: ihf is a safe and reliable procedure for reconstructing head and neck surgical defects. due to its thinness and malleability, its use for oral cavity and oropharynx defects provides favorable cosmetic and functional outcomes. complications, when present, are easy to manage.

Abstract: The university monitoring is an auxiliary activity of educational support offered to students interested in deepening content and solving questions about the topics learned in the classroom, as well as an opportunity for the development in the student-monitor relationship next to the teaching practice. This study aimed to report the experience lived by the student-monitors linked to monitoring project entitled “Interdisciplinary for improving the quality of education: Physiology, Anatomy and Pathology for Clinical Nursing teaching”. It is an experience report experienced by student-monitors linked to the project developed for curriculum component Comprehensive Health Care I, taught in the fifth period of the Undergraduate Nursing course at the Federal University of Rio Grande do Norte, Brazil. This project has four stages: preparation of laboratories and fellows training, construction and application of clinical cases, development of simulations in the laboratory with the students and the final evaluation of the changing process in curriculum practice. The monitoring project has provided contact with a simulation environment for students, for the development of skills and attitudes in solving clinical nursing problems through an innovative approach to integrating disciplinary learning in the classroom and development initiation skills in student-monitors teaching. The approximate relationship with the teacher allows the exchange of knowledge, which makes proactive student-monitor in the very process of teaching and learning, as well as the teacher provides the formation of a more qualified and secure professional for the exercise of appropriate assistance.

Abstract: this work describes the chemical composition of the volatile oil of hyptis marrubioides cultivated in field and greenhouse. the experimental design was completely randomized, with ten replications for each type of cultivation. the volatile oil was extracted by hydrodistillation and analyzed by gc-ms. the highest content of volatile oil was found for plants grown in field. the highest percentage of the compounds present in oils was observed in samples grown in the field, such as germacra-4(15),5,10(14)-trien-1-α-ol (16.34%), β-caryophyllene (10.42%), γ-muurolene (12.83%) and trans-thujone (9.98%). however, some compounds were found only in plants grown in a greenhouse, such as cis-muurol-5-en-4α-ol (10.84%), α-cadinol (3.06%) and eudesma-4(15),7-dien-1β-ol (6.82%).
